But the more she listened to it, the more she realized "it's really a love song."

"I'm truly just the happiest I've ever been," she told us.

Ballerini said her new music also represents the changes the singer has gone through since first moving to Nashville at 19.

"I wrote my first record when I was 19-years-old [and] I put it out when I was 21, and I'm 23 now," she shared ahead of her Colgate Optic White show in New York City. "So I just feel like being able to finally put out music that is who I am right now, is really fun for me because I've just changed a lot, I've grown up a little bit and I just have a different perspective on life."

Ballerini said her faith and family have kept her grounded through this process.

"I think that the beautiful thing about country music is everyone is kind of brought up the same way and so growing up...on a farm, growing up going to church every Sunday and then having a big meal with my family afterwards," she shared. "All of those things made me a country songwriter a country singer. I think 90 percent of country artists are raised the same way and I think that's part of what makes country music, country music."
